ppmtowinicon - convert 1 or more portable pixmaps into a Windows .ico
file
ppmtowinicon [-andpgms] [-output output.ico] [ppmfiles...]
Reads
one or more portable pixmaps as input. Produces a Microsoft Windows .ico
file as output.
A Windows icon contains 1 or more images, at different
resolutions and color depths.
Microsoft recommends including at least
the following formats in each icon.
16 x 16 - 4 bpp
32 x 32 - 4 bpp
48 x 48
- 8 bpp
Default I/O is STDIN/STDOUT.
- -andpgms
- If this option is given,
every other file is read as an alpha mask to be used by windows for transparancy
data for the previous image. (These are set to blank by default). The alpha
mask is a PGM image, where any value less than or equal to the maxval means
transparent, and anything greater than the maxval means opaque. Note that
as with all Netpbm programs, you may use a PBM file here and it will be
used as if it were the equivalent PGM.
- -output output.ico
- File to write.
By default, the icon is written to stdout.
